"Earth's Biggest Bookstore, now offering 2.5 million titles, "opened its doors" on the World Wide Web in July 1995. Amazon.com has quickly become not only the leading online retailer of books, but also one of the most widely used and cited commerce sites on the World Wide Web. With more than 1.5 million unique customers, Amazon.com strives to offer compelling value through broad selection, high-quality content, a high level of customer service, competitive pricing, personalized services, and innovative use of technology." This is the place to buy your books. The whole catalogue is searchable and their prices are lower than you can usually find at the corner bookstore. Highly recommended.
